ChromoTune is a chromatic tuner for every instrument — guitar, bass, violin, cello, ukulele, brass, woodwinds, and voice.
A swordfish hangs steady while the dial drifts behind it, showing how sharp or flat you are at a glance. Land in tune and it settles.
• Chromatic — tunes any note, any instrument
• Fast, accurate pitch detection
• Adjustable reference pitch, A from 415 to 466 Hz
• Two themes: Tuna and Aquarium
• Calm and uncluttered — no accounts, no distractions
• Free
Allow the microphone, play a note, and tune.
